A fine and rare pair of doucai 'shou' bowls marks and period of Yongzheng

well potted with rounded sides sitting on a short straight foot, finely painted to the exterior with four leafy longan boughs each bearing one yellow and one green fruit, the yellow fruits enclosing a shou character, separated by four pairs of iron-red bats, the interior painted with a central medallion of five bats, wufu, and a fruiting peach branch issuing from a rocky cliff above crested waves, the base with a six-character mark in underglaze-blue within a double circle

Doucai bowls of this design are extremely rare, although the motif of bats and the shou characters can be found on Yongzheng birthday dishes, see one illustrated in Rose Kerr, Chinese Ceramics, London, 1986, pl. 86, from the Victoria and Albert Museum collection.
